  • Patent number: 8878035
    Abstract: A string depressing device is useable to fret at least one string of a stringed musical instrument. The string depressing device includes a frame that, when adjacent to a fingerboard of the stringed musical instrument, extends both along and across the fingerboard and above the strings. A plurality of protruding compressible resilient members extend from the frame toward the fingerboard. When the frame is pressed against the fingerboard, each protruding member sufficiently depresses an underlying string to fret that string. In an operative position, some of the protruding members are positioned over corresponding strings at desired positions along the fingerboard. A capo can be placed around the neck of the stringed instrument and over the frame to press the frame towards the fingerboard. This presses at least some protruding members against corresponding strings, and effectively frets those strings against the fingerboard at the desired positions to form a musical chord.

Three pushbutton assemblies are provided, each of which depresses three strings on a musical instrument. The pushbuttons are color coded to correspond to colored indicia provided on the sheet music.

  • Patent number: 4553466
    Abstract: There is disclosed a lever apparatus which is adapted to be used on the neck of a musical instrument such as a guitar or other string instrument. The apparatus contains a plurality of spring biased lever arms each of which are pivotally mounted to a common rod by means of an associated U-shaped member. Each lever arm is directed parallel to an associated string of the instrument and has at one end an elastomeric pad which is positioned in a first position to be out of contact with the string. In a second position the user applies pressure to the lever arm with his finger which moves the pad into contact with the string. As soon as pressure is released, the spring automatically returns the arm to the first position. By using the common rod, multiple arrays of such lever arms can be mounted on the neck of the instrument to enable the user to access any string as well as at different fret locations.

  • Patent number: 4545281
    Abstract: A device for adjusting chords in string instruments wherein elements for effectively shortening the musical length of a string are disposed on the instrument for taking over the former function of the fingering hand for the use in playing chords or tones. The desired chords are electrically stored and are read back by operating elements from programmable and exchangeable memories by pulses to the corresponding string shortening elements so that the pitch of the strings is changed and by this the desired chord is adjusted on the instrument. The operating elements make the selection of chords and their variations possible and the chord sequences can be adjusted by actuating a simple push button. A display is provided to facilitate the selection by the musician from the various programs and to give an understanding as to which chord has been selected. Means are also provided for dampening the strings so that rhythm effects can be obtained.

  • Patent number: 4545282
    Abstract: A button actuated chord selector and playing device for simultaneously pressing a plurality of selected strings of a stringed musical instrument, such as a guitar, against the spaced frets of the instrument to shorten the vibrational length of the strings, to increase the pitches of the instrument, and, thereby, to produce selected harmonizing chord sounds. Each button operates its related actuating bar extending parallel with the neck of the instrument, and each of those actuating bars is operably connected to actuate a plurality of transversely extending selector bars positioned at different positions longitudinally on the neck of the instrument to engage and press selected strings against the spaced frets to produce the selected chord. Laterally spaced guide pins are provided at opposite ends of the actuating and selector bars to limit movement of the bars and to keep opposite ends of the bars moving in unison.

  • Patent number: 4112805
    Abstract: A device mounted on the neck of a stringed musical instrument such as a guitar, to facilitate the playing of chords on the musical instrument. The device includes a housing reciprocably mounted on the neck of the musical instrument above the strings thereof. Rotatably mounted in the housing are a plurality of drums having fixed stops provided in spaced predetermined locations about the circumference of each drum. When the housing is depressed towards the neck, the stops will stop the strings in predetermined locations so that strumming of the strings will produce an appropriate chordal note. A pinion is connected to one end of each of the drums which is placed in meshing engagement with a rack slidable through the housing by the fingers of the hand of the player to rotate the drums and reposition different combinations of stops relative to the strings of the instrument for changing the chordal note produced by the instrument.
